The earliest designs were simple affairs, often mere "foot bags" of leather to protect the feet from rocks, debris, and cold.Since shoes use more leather than sandals, their use was more common in cold climates.Soles, which were once laboriously hand-stitched on, are now more often machine stitched or simply glued on. Most boots mainly cover the foot and the ankle and extend up the leg, sometimes as far as the knee or even the hip.Most boots have a heel that is clearly distinguishable from the rest of the sole, even if the two are made of one piece.Toes became long and pointed, often to ridiculous proportions.
Until around 1800, shoes were made without differentiation for the left or right foot. Only gradually did the modern foot-specific shoe become standard.
"A shoe is not only a design, but it's a part of your body language, the way you walk.
"A shoe has so much more to offer than just to walk." - Christian Louboutin. But the shoe carries the woman." - Christian Louboutin.
However, tanned leather, the material most commonly used for making shoes, does not normally last for thousands of years, so shoes were probably in use long before this.
Physical anthropologist Erik Trinkaus believes he has found evidence that the use of shoes began in the period between about 40,000 and 26,000 years ago, based on the fact that the thickness of the bones of the toes (other than the big toe) decreased during this period, on the premise that wearing shoes resulted in less bone growth, resulting in shorter, thinner toes.
